Applications of film capacitors
*Application in power electronic circuit. Film capacitors are used mainly for buffering and clamping of power currents, resonant bypass, and suppression of electromagnetic interference from power supplies.
*When the film capacitor is used as a bypass, it mainly serves to reduce the impedance of the DC bus and absorb the ripple current from the load, thus effectively suppressing the fluctuation of the DC bus voltage due to sudden changes in the load.
*When the device is used in a resonant converter, it is able to achieve resonance with the inductor.
Precautions when applying film capacitors
*First of all, it is necessary to carefully observe the state of the operating voltage, and when the operating voltage is very unstable, do not use film capacitors in the first place.
*If the operating voltage is unstable, do not use the film capacitor.
*The RMS current and peak current of the capacitor should be satisfied.
